King of FM: A Free FM Synth App For iOS/macOS

King Of FM, is a free software synth for iOS and Mac that is based on the sounds of vintage ’80s FM synths by the Yamaha DX7, DX7II, TX81z, and SY77. It has been released by Matthew Fetcher, one of the core developers of Audiokit, a development environment in which developers can publish iOS apps.

According to Matthew, he sampled a legendary-sounding DX7II from a famous studio. He then released an app called FM Player, packed with those samples.

The response from musicians? Stupidly incredible. We received literally thousands of emails from grateful musicians. One message read “This app filled my eyes with tears when I first played through the sounds. It brought back memories of my youth, I was transported to a time when anything and everything was possible.”

Now, you can have these sounds on iPhone and Silicon Macs. (FM Player was only available on the iPad). Plus, King of FM is more stable as an iOS/iPadOS AUv3. You can have multiple instances of this app in GarageBand, AUM, Cubasis, BeatMaker or your favourite iOS DAW.
